Gastrointestinal Motility Disorders01:20

Gastrointestinal Motility Disorders

212
Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...

Parkinson's Disease: Overview01:15

Parkinson's Disease: Overview

334
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Disorders of the Nervous Tissue

960
Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.
Homeostatic Imbalances:
Alzheimer's disease manifests as a gradual decline in memory and cognitive abilities, attributed to the buildup of amyloid plaques and neurofibrillary tangles in the brain.

Disorders of the Skeletal Muscle

832
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Neural Regulation01:37

Neural Regulation

39.0K
Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Positive Symptoms of Schizophrenia: Hallucinations and Delusions01:30

Positive Symptoms of Schizophrenia: Hallucinations and Delusions

39
Schizophrenia is a complex mental health disorder that can manifest with various positive symptoms, including thought, movement, and behavior disorders. These symptoms significantly disrupt cognitive and motor functions, leading to profound effects on an individual's ability to engage with the world.
Thought Disorders
Disorganized and unusual thought processes mark thought disorders in schizophrenia. One key feature is disorganized speech, where an individual's conversation includes...

Area of Science:

  • Neuroscience
  • Neurology
  • Speech-Language Pathology

Background:

  • Swallowing is a complex sensorimotor function vital for health and quality of life.
  • Neurologic conditions frequently cause swallowing disorders (neurogenic dysphagia) due to widespread neural control.
  • Current dysphagia classification lacks a framework considering the sensorimotor hierarchy and underlying neuropathology.

Purpose of the Study:

  • To explore neurogenic dysphagia using sensorimotor hierarchy and movement disorders terminology.
  • To provide evidence of dysphagia in movement disorders and discuss assessment nuances.
  • To advance clinical management and research in neurogenic dysphagia.

Main Methods:

  • Literature review focusing on sensorimotor control of swallowing.
  • Analysis of dysphagia signs and symptoms in movement disorders.
  • Discussion of neuropathological bases of oropharyngeal swallowing biomechanics.

Main Results:

  • Neurogenic dysphagia classification is lacking a sensorimotor hierarchy framework.
  • Movement disorders present specific dysphagia signs and symptoms.
  • Assessing neuropathology is crucial for understanding disordered swallowing biomechanics.

Conclusions:

  • A sensorimotor hierarchy framework is needed for neurogenic dysphagia.
  • Detailed assessment of underlying neuropathology can improve dysphagia management.
  • This approach will advance identification and treatment strategies for neurogenic dysphagia.
